9 Claims. (Cl. 20-71) This invention relates to window gratings for useupon houses and other buildings to prevent would-be intruders fromentering through windows or other openings.

The present invention contemplates a construction whereby the gratingbars may be securely locked in the windowy barring position when theirprotection is desired, and may be easily and quickly moved to aninactive position 1'0 adjacent the sides of the window, where they aremore or less out of sight, when their protection is not wished.

One feature of the present invention resides in a window grating havingguide strips or rails l5 secured to the window frame at the oppositeends of the grating bars to support them -for sliding movement to andfrom the window barring position,v and provided with a central guiderail secured across the window toslidably support 201 these bars betweentheir ends, and also having means associated with the central guide railto lock the grating bars to this rail to prevent the bars from beingforced out of place.

A more speciiic feature of the present inven- 25 tion resides in theconstruction for locking the grating bars to the central guide rail tothereby retain these bars in the window barring position so that theycannot be sprung apart or moved y longitudinally or transversely of theguide rail. 30' A further featureresides in grating bars connected bybraces to operate in sets and to brace one bar from another, and inmeans for supporting these sets for sliding movement and also forswinging movement about the axis of one bar so 'that the grating barscan be swung back away from the window adjacent Vthe wall of thebuilding.

Other features of the invention and novel combination of parts inaddition to the above will 59 be hereinafter described in connectionwith the accompanying drawings which illustrate good practical forms ofthe invention. f

The window grating of the present invention 0 may be. used in windows ofthe ordinary home or other buildings and may be readily installed in newor old windows where their protection is desired. The window frame whichmay be of usualV construction has the sides I0, top portion II andbottom portion or sill I2, and in the frame are slidably mounted theupper and lower sashes I3, both sashes being shown raised in Figs. 1, 9,and 10.

In the embodiment of the invention shown in Figs. 1 to 8, inclusive, thegrating bars I4 are independently movable, and when their protection isnot desired may be moved to the sides of the window, that is, two toeach side of the window, where they are stored one against the other,out of the way and out of View from the outside o1v the window.Y Thegrating bars I4 may or may not be provided with heads atrboth ends andare shown as provided with heads I 5 at the upper ends but none at thelower ends. Y

These bars I4 are slidably supported at their opposite ends by guidestrips or rails I6 and I1 which are channeled in the'constructionshownto slidably receive the upper heads I5 and lower ends of the bars I4.The upper rail I5 is shownV 45 as secured by screws I8 to the topportion II ofV the window and the lower rail Il is shown as secured byscrews I9 tov the window sill I2. The upper rail I6 is provided withpockets 20 along its length adapted to receive the heads I5 to hold 50the upper ends of the bars I4 in the window b-arring position, and thelower rail Il is provided Y with the pockets 2| adapted to receive thelower ends of the bars I4 and hold them in the window barring position.55

1 mediate unslotted portion of the bar Ywill enter VthenotchV V23 4sothat if the bars I4 are locked in this lowered position they will beheld against f5`5 lowered position just mentioned comprisesV a Y cuttingnotches in these ribs as Yshown in Fig. 2.

The lower rail I1 is; shown as trough or U-shape in crosssection and thepockets 2| are formed by providing holesin the bottom of this rail toreceive the ends of the bars I4. Y

-If the bars I4 are relatively long ably receive the intermediateportion of the bars I4 and lock'them in the window barring position.

The central rail 23 in the construction shownhas VVthe forni of a hollowtuberectangular in cross sectionand has formed in its upper and lowerWalls theY longitudinally extending slots 24 and 25 extending fromranunslotted central portion 26 of the rail to'near the ends of therail.-and Y permit the Ybars I4 to slidealong the slots 24 and V25 from astored positionadjacent thesides o1 the window to the window barringposition.

The central rail 23 in'the kconstruction shown serves Vto lock the barsin spaced relation kto each other and also to hold the ends of theseVbars'in Vthe pocketsiZIJ, 2|. shown as square in' cross section and asprovided at their central Vportion with a transversev locking Thegrating bars I4 are slot 21 adapted to slide in the longitudinal upperslot'Y 24 Lof* the rail 23. Thelower longitudinal slot 25, it should benoted, is wider than the slot 24 and slidably receiveslthe Vunslottedportion of As a result of this construction the theV bar fI4. t verticalsliding movement of Ythe bars I4 is limited by the width ofthe slots 21.

Y In order to lock Vthe bars against sliding movementalong the slots 24each of these slots isprovided with the -bar receivingnotches28positioned to retain the bars in the window barring position.

The arrangement is such that when a bar I4 is movedrto its windowbarring position its Yends` will drop intothe Vpockets 20,`2I and anintermovement Vboth longitudinally and transversely. The means shownrforlocking each bar v I4 in the locking strip, 29 slidably mounted inthehollow rail 23 for` movement into and out ofthe notches 21. Thisstripmay be shifted byakey controlled lock 30 to and from thebar lockingposition.` The lock 30 is .conveniently mounted in the solidportionf26of the rail 23 and has a revolving barrel at the inner end of whichissecured an eccentric 3l adapted to coi-operate with projections 32 onVthe strip 29 to shift this strip. Pins 33 mounted in the rail V23V andextending through. inclined slots A3l! in the strip 29 guide-thisstrip.along a diagonal path as it isshifte'd by the lock to move thestrip from its bar locking position of Figs. 4

and 5 to its'bar Yreleasing position of Figs.f6, 7.' I e' and'S.

It will be seen from theforegoing that when the grating bars I4 aremoved to the position in,

' "whichthey Vare shown in Fig. 1 and lowered into the proper pockets20'and 2 I, they may be locked it is desirable Vto provide means forbracing or connecting'them`V Y between their ends to prevent the barsfrom being Vsprung out of place, and this is'accomplished the'construction shown in Figs. 1 to 8,1inclusive, byproviding thecentral'rail 23 adaptedto slid?r in this position by operating the lock30 to move Y the strip 29 to the bar locking position. y Y Y In themodification shown in Figs. 9 to V13,

inclusive, the grating bars V` are connected by `the Ytransverse braces36Y to Voperate Vin sets or 5 pairs so that one bar braces another toprevent the bars from being sprung out of place. yThe bars 35 areprovided with heads 31 at their ends Y adapted to slide in the channeledguide rails 38 and 39.` The upper rail 38 may V.be constructed the sameas theupper rail I6 above'describedand f is provided along itslength'with' pockets similar Y tothe pockets 20 adapted to receivetheheads 31VV to hold the bars in the windowbarring position. `The lowerguide rail 39. has the rectangular shapeA in cross sectionbest shown inFigfll'rand in its upper face is formed a longitudinally ex- Vtendingslot 40 in which the bars 35 slide. In

the lower wall of the channeled rail 39 are formed the, pockets 4Iadapted to receive thev heads 31 20 when thebars are moved to the window.barring position and dropped in theV pockets of the upperV andlower'rails. Y The lower rail is shown as'havf ing a locking strip 42and key controlled look-4,3 mounted in` a central Vunslotted portionofthe rail 39,- similar to the strip;29`and lock 30 above described. Thearrangement is such that the lock 43 maybe operated to moveth'e strip]42 from its inactive positionV in which it is shown-ln Figs; 12 and 13to its locking position of Fig. 11. In Fig. 11 it will be seen that thehead'31 lies within the pocket 4I and the Vstrip 42 overlies a portionof the head Vto lock the bar heads in the kpockets in the upper andVlower guide rails to secure-the bars' Sincethebars 35 are connected tooperate inV sets orY pairs they can not be stored one against the otheratr theHsides of the Window as in thev construction of Fig. 1.l Fig. 12Ytherefore shows'a construction whereby the rigidly connected bars 40Vafter being moved tothe sides of the window mayV be swungrabout theaxis of one bar outwardly away from the window sashes to a storedposi-,-V tion adjacent the inner wall of the room as will in the windowbarring position.
